Three-Year Outcome Data of Second-Line Antiretroviral Therapy in Ugandan Adults: Good Virological Response but High Rate of Toxicity
Bibliographic record
Abstract
OBJECTIVE: To evaluate the safety and virological response to lopinavir/ritonavir containing second-line therapy after failing a first line nonnucleoside reverse transcriptase inhibitor (NNRTI) based regimen. DESIGN: Prospective 36 months cohort study of patients switched to zidovudine/stavudine plus didanosine plus lopinavir/ritonavir capsules as second-line regimen. METHODOLOGY: Structured interview, medical examination, and laboratory assessment performed every 6 months. RESULTS: We enrolled 40 patients; 1 died and 3 were lost to follow-up. Median CD4+ count at baseline was 108 cell/microL, median log viral load was 4.8 copies/mL. Sixteen (40%) patients had baseline genotypic resistant test, 14 (87%) had lamivudine resistance mutations, and all had NNRTIs resistance mutations. At month 36, 82% of the patients achieved viral suppression (<400 copies/ mL) and the median increase in CD4+ count was 214 cell/microL, (interquartile range: 128-295). Twenty-five patients (62%) experienced at least one adverse event. CONCLUSIONS: Our study confirms lopinavir/ ritonavir-based second-line regimen but with a high rate of toxicities.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
